So I bought a second hygrometer because even after I put the lil jar with a sponge in it it still only was 35%. So my new, new one (my 1st one is brand new too!) says 70%. I can't believe it's like 25% off! I'm going to calibrate the 1st one tonight with the wet salt in a bag, then calibrate the 2nd one tomorrow. It's been hard keeping my humidity up at 65% so how do you raise it even higher for lock down?.....put a second container of water with a sponge in it? What about vent plugs, in or out? Also I wanted to know how much of the sponge should be sticking out of the water? I'm incubating duck eggs in a still air in case anyone is wondering about the high humidity.
Is this set up ok for optimum humidity readings?........
Here you can see the lil square hygrometer on top of the eggs. Then the white hanging wire from my digital hygrometer/thermometer & the thermometer that came with my bator is on top of the other eggs. Also the jar w/ sponge.

Days 1-18 should be in the low to mid 30's for humidity and they bump up to the mid 60's for lockdown.
